On facebook privacy settings . . . What is the diffrence between "Friends Only" & "Friends of Friends"?

[gentledime296]

Does friends of friends mean that even thought we are not friends as long as we have mutual friends you can see my information?

[Becky Schulz]

yes, it does.

if you choose frineds only, then only your friends can see it [dur]
if you choose friends of friends, then your friends' friends can see, even if you aren't friends,
and then maybe their friends could see :/

it gets very complicated.
